Vehicle Speed Sensor (VSS) On vehicles equipped with 4-wheel anti-lock brake systems (4WABS), the vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4WABS module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems that require a vehicle speed signal input. P1dab-00,u1412,p0716. Vehicle has shown codes above for 5 plus months. Codes cause vehicle to shift between gear randomly. I have taken vehicle to dealership but probably was not resolved; the dealership stated the problem was the speed sensor, so the switched them out only to find out later it was not the problem. Locate the wheel speed sensor behind the brake rotor and remove any debris or dirt surrounding it. 2. Use a sensor-safe cleaner to spray the sensor, ensuring all visible contaminants are removed. 3.

A Harley speed sensor is a device that measures the rotational speed of the wheels on a Harley-Davidson motorcycle. The sensor is typically located on the transmission or the wheel hub and works by using a magnet and a Hall effect sensor to generate an electrical signal. As the wheel rotates, the magnet passes by the sensor, causing a change in i am having vehicle speed sensor problems on my 2000 silverado 4.8 with 4l60e transmission. i have put new vss,reluctor ring,brake pump & module,wheel bearings,abs wheel speed sensors, and a new wire … l63ETp.
